Two world-renowned scientists present an audacious new vision of the cosmos that “steals the thunder from the Big Bang theory.” —Wall Street Journal The Big Bang theory—widely regarded as the leading explanation for the origin of the universe—posits that space and time sprang into being about 14 billion years ago in a hot, expanding fireball of nearly infinite density. Over the last three decades the theory has been repeatedly revised to address such issues as how galaxies and stars first formed and why the expansion of the universe is speeding up today. Furthermore, an explanation has yet to be found for what caused the Big Bang in the first place. In Endless Universe, Paul J. Steinhardt and Neil Turok, both distinguished theoretical physicists, present a bold new cosmology. Steinhardt and Turok “contend that what we think of as the moment of creation was simply part of an infinite cycle of titanic collisions between our universe and a parallel world” (Discover). They recount the remarkable developments in astronomy, particle physics, and superstring theory that form the basis for their groundbreaking “Cyclic Universe” theory. According to this theory, the Big Bang was not the beginning of time but the bridge to a past filled with endlessly repeating cycles of evolution, each accompanied by the creation of new matter and the formation of new galaxies, stars, and planets. Endless Universe provides answers to longstanding problems with the Big Bang model, while offering a provocative new view of both the past and the future of the cosmos. It is a “theory that could solve the cosmic mystery” (USA Today).

This is the first serious challenge to the widely accepted 'Big Bang' model of the universe. According to 'Big Bang' theory, space and time sprang into existence fifteen billion years ago: a super-heated fireball of near infinite density that expanded at phenomenal speed. As it continued to expand, it cooled and condensed to create the galaxies, stars and planets we see today. But the theory has always had flaws and they have become increasingly difficult to reconcile. Why is the distribution of matter and radiation in the universe so uniform? Why is space flat rather than curved, as Einstein's theory of general relativity suggests? And where did the seeds for forming galaxies come from? To resolve these issues, Turok and Steinhardt propose a very different model of the universe. They argue that it is without beginning or end, truly an ENDLESS UNIVERSE. There is a continual cycle of expansion and contraction as parallel universes (or 'branes') collide. In this highly accessible book, they chronicle that last thirty years of cosmology as scientists tried to make the Big Bang theory account for recent discoveries in cosmology. They explain the discovery of 'dark energy', 'dark matter' and the evolution of their new model of our universe. Finally, they address the question of when the next collision might occur between our worlds and the parallel dimensions in space.

Ist das Universum unendlich oder begrenzt? Hat die Raumzeit einen Anfang, den Urknall? Dehnt sie sich aus? Wird sie wieder in sich zusammenstürzen? Liefe die Zeit dann rückwärts? Welchen Platz im Universum nehmen wir ein? Und ist in den atemberaubenden Modellen der Kosmologen noch Platz für einen Gott? – Es sind existenzielle Fragen, mit denen sich Stephen Hawking befasst, Fragen, die Forschung und Lehre in den Zentren der modernen Physik ebenso bestimmen wie die Diskussion von Geisteswissenschaftlern. Dieses Meisterwerk eines Jahrhundert-Genies hat unsere Weltsicht verändert. Zugleich hat Stephen Hawking damit neue Maßstäbe für die Erklärung komplexer physikalischer Zusammenhänge gesetzt. In diesem Buch, weltweit inzwischen über zehn Millionen Mal verkauft, ist das Credo des großen Physikers enthalten und lebendig. «Der Physiker Stephen Hawking ist im Begriff, die Formel zu finden, die das Universum erklärt.» ZEIT-Magazin

Peter Unger's provocative new book poses a serious challenge to contemporary analytic philosophy, arguing that to its detriment it focuses the predominance of its energy on "empty ideas." In the mid-twentieth century, philosophers generally agreed that, by contrast with science, philosophy should offer no substantial thoughts about the general nature of concrete reality. Leading philosophers were concerned with little more than the semantics of ordinary words. For example: Our word "perceives" differs from our word "believes" in that the first word is used more strictly than the second. While someone may be correct in saying "I believe there's a table before me" whether or not there is a table before her, she will be correct in saying "I perceive there's a table before me" only if there is a table there. Though just a parochial idea, whether or not it is correct does make a difference to how things are with concrete reality. In Unger's terms, it is a concretely substantial idea. Alongside each such parochial substantial idea, there is an analytic or conceptual thought, as with the thought that someone may believe there is a table before her whether or not there is one, but she will perceive there is a table before her only if there is a table there. Empty of import as to how things are with concrete reality, those thoughts are what Unger calls concretely empty ideas. It is widely assumed that, since about 1970, things had changed thanks to the advent of such thoughts as the content externalism championed by Hilary Putnam and Donald Davidson, various essentialist thoughts offered by Saul Kripke, and so on. Against that assumption, Unger argues that, with hardly any exceptions aside from David Lewis's theory of a plurality of concrete worlds, all of these recent offerings are concretely empty ideas. Except when offering parochial ideas, Peter Unger maintains that mainstream philosophy still offers hardly anything beyond concretely empty ideas.

"Multiverse" cosmologies imagine our universe as just one of a vast number of others. While this idea has captivated philosophy, religion, and literature for millennia, it is now being considered as a scientific hypothesis—with different models emerging from cosmology, quantum mechanics, and string theory. Beginning with ancient Atomist and Stoic philosophies, Mary-Jane Rubenstein links contemporary models of the multiverse to their forerunners and explores the reasons for their recent appearance. One concerns the so-called fine-tuning of the universe: nature's constants are so delicately calibrated that it seems they have been set just right to allow life to emerge. For some thinkers, these "fine-tunings" are evidence of the existence of God; for others, however, and for most physicists, "God" is an insufficient scientific explanation. Hence the allure of the multiverse: if all possible worlds exist somewhere, then like monkeys hammering out Shakespeare, one universe is bound to be suitable for life. Of course, this hypothesis replaces God with an equally baffling article of faith: the existence of universes beyond, before, or after our own, eternally generated yet forever inaccessible to observation or experiment. In their very efforts to sidestep metaphysics, theoretical physicists propose multiverse scenarios that collide with it and even produce counter-theological narratives. Far from invalidating multiverse hypotheses, Rubenstein argues, this interdisciplinary collision actually secures their scientific viability. We may therefore be witnessing a radical reconfiguration of physics, philosophy, and religion in the modern turn to the multiverse.

In this visionary book, Neil Turok explores the great discoveries of the past three centuries - from the classical mechanics of Newton; to the nature of light; to the bizarre world of the quantum; to the evolution of the cosmos; and even the recent findings of Higgs bosons at the Large Hadron Collider. Each new discovery has, over time, yielded new technologies that have transformed society. Now, he argues, we are on the cusp of another major change: the coming quantum revolution that will supplant our digital age. Facing this new world, Turok calls for creatively re-inventing the way advanced knowledge is developed and shared, and opening access to the vast, untapped pools of intellectual talent in the developing world. Scientific research, training, and outreach are vital to our future economy, as well as powerful forces for peaceful global progress. Elegantly written and highly inspirational, The Universe Within is, above all, about the future - of science, of society, and of ourselves.

Wie wirklich ist Zeit? Zeit ist etwas völlig Selbstverständliches für uns, wir erleben, wie sie vergeht, wenn wir auf die Uhr schauen, Kindern beim Älterwerden zusehen oder Wettrennen beobachten. Und doch haben Physiker von Newton über Einstein bis zu den heutigen Quantenphysikern eine andere Auffassung der Zeit. Für sie ist sie nicht real, sondern eine Illusion. Für sie wird das Universum von Gesetzen beherrscht, die außerhalb der Zeit stehen, zeitlos sind, von Newtons Gravitationsgesetz bis zur Formel e=mc2. Lee Smolin hingegen sieht Zeit als die einzige fundamentale Größe des Universums. Alles andere, auch die vermeintlich unabänderlichen Gesetze, unterliegen seiner Auffassung nach der Veränderung in der Zeit. Newtons Gesetze werden vielleicht nicht immer so grundlegend bleiben, wie wir sie heute verstehen. Mit dieser revolutionären Auffassung stellt er die Zeit in den Mittelpunkt unseres Denkens über die Welt und erklärt, welche Auswirkungen das auf uns, auf die Welt, auf das Universum hat.
